Symfony3 - 左连接无法正常工作
尝试使用加入Symfony3解决此问题。
结果集以某种方式混合了值，即
ID Exploit Author
ID Author Author
请参阅随附的屏幕截图。
OpenX应该有Author Metasploit，第二行不应该在那里。
在控制器中输入此代码：
public function indexAction()
{
$exploits = $this->getDoctrine()
->getRepository('AppBundle:Exploit')->createQueryBuilder('e')
->add('select', 'a,e')
->add('from', 'AppBundle:Exploit e')
->leftJoin('AppBundle:Author', 'a')
->where('e.author = a.id')
->getQuery()
->getResult();
return $this->render('exploit/index.html.twig', array(
'exploits' => $exploits
));
}
这个观点：
<tbody>
{% for exploit in exploits %}
<tr>
<th scope="row">{{ exploit.id }}</th>
<td>{{ exploit.name }}</td>
<td> {{ exploit.author }} </td>
<td>
<a href="/details/{{ exploit.id }}" class="btn btn-success">View</a>
<a href="/edit/{{ exploit.id }}" class="btn btn-default">Edit</a>
<a href="/delete/{{ exploit.id }}" class="btn btn-danger">Delete</a>
</td>
</tr>
{% endfor %}

有人知道如何更正我的加入查询吗？或者为什么它会像这样？
谢谢，
2 个答案:
答案 0 :(得分：1)
试试这个：
->leftJoin('AppBundle:Author', 'a', "WITH", "e.author = a.id")
而不是：
->leftJoin('AppBundle:Author', 'a')
->where('e.author = a.id')
答案 1 :(得分：0)
尝试
public function indexAction()
{
$exploits = $this->getDoctrine()
->getRepository('AppBundle:Exploit')->createQueryBuilder('e')
->leftjoin('e.author','a')
->addSelect('a')
->getQuery()
->getResult();
return $this->render('exploit/index.html.twig', array(
'exploits' => $exploits
));
}
并在视图中
<tbody>
{% for exploit in exploits %}
<tr>
<th scope="row">{{ exploit.id }}</th>
<td>{{ exploit.name }}</td>
<td> {{ exploit.author.name }} </td>
<td>
<a href="/details/{{ exploit.id }}" class="btn btn-success">View</a>
<a href="/edit/{{ exploit.id }}" class="btn btn-default">Edit</a>
<a href="/delete/{{ exploit.id }}" class="btn btn-danger">Delete</a>
</td>
</tr>
{% endfor %}
